BINDER-TWINE-CURING MACHINE.

Specification of Letters Patent.

Patented May 19, 191.4.

Application filed May 9, 1913. Serial No'. 766,646.

To all whom it may concern Be it known that I, JOHN J. LANDSBERGER,citizen of the United States1 residing at the town of Douglas, in thecounty of Dakota and State of Minnesota, have invented certain new anduseful Improvements in Binder- Twine-Curing Machines, of which thefollowing is a specification.

The present invention relates to an improved machine for treating twineand the like with a preservative Huid, the object of the invention beingto provide a device of this character which embodies novel features ofconstruction whereby it may be readily mounted upon a binder or the likeso as to treat the twine as it passes to the binder and at the same timemaintain the twine under the proper' tension for the etfective operationof the binder.

A further object of the invention is to provide a twine curing machinewhich is comparatively simple and inexpensive in its construct-ion,which is economical in the use of the preservative fluid, which has acompact arrangement of the parts, and which serves to produce thenecessary tension in the twine and to remove all superfluous quantitiesof the preservative fluid from the twine before it finally emerges fromthe machine.

With these and other objects in view, the inventionconsists in certainnovel combinations and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in which Figure 1 is alongitudinal sectional view through a twine curing machine constructedin accordance with the invention. Fig. 2 is a transverse sectional viewon the line 2-2 of Fig. 1. Fig. 3 is a horizontal sectional view on theline 3-3 of Fig. 1. Fig. 4 is a similar view on the line lllat of Fig.l, and Fig. 5 is a side elevation of the tension box which is applied tothe inside of the cover and acts upon the twine as it enters the tank.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Specifically describing the present embodiment of the invention, thenumeral l ('.Iesignates the casing within which the tank 2 is mounted,the said casing being of any suitable size and shape and being normallyclosed by means of a cover 3. The mouth of the casing 1 is shown asprovided with an inwardly projecting flange 4t upon which 'the edge ofthe cover 3 rests, a suitable packing member 5 being interposed betweenthe edge of the cover and the flange so as to produce a tight joint andprevent the preservative fluid G within the tank from splashing out ofthe device. Any suitable means may b e provided for retaining the cover3 in position upon the casing, although in the present instance a pairof transverse securing strips 7 are ,shown as applied to opposite endsof the cover, the extremities of the securing strips 7 having the haspmembers 8 hinged thereto for engagement with staples or like members 9which project from the sides of the casing 1. Cotter-pins 10 or similarfastening members may be employed for normally retaining the hasps 8 inengagemeut with the staples 9, and it will be obvious that by removingthose Cotter-pins 10 upon one side of the casing l, the cover 3 will bereleased at one edge thereof so that it can be readily swung upwardlyabout the hasp members 8 at the opposite edge thereof as a pivot. Accessmay thus be readily had to the interior of the easing l and tank 2without the necessity of entirely removing the cover 3 from the casing,although the cover may be completely detached from the casing at anytime should this be found desii-able.

A pair of guide openings 11 and 12 are formed in the cover 3, the twine13 entering the casing` through the guide opening 11 and leaving thecasing through the guide opening 12 after having passed around thegrooved wheel 14 and been immersed thereby in the preservative fluid G.This immersing wheel 14 is journaled within suitable bearings 15 upon aU-sliaped bracket 16 the arms of which have the extremities thereofsecured to the lower face of the cover 8 while the lower transverse endportion of the bracket is substantially horizontally disposed and isslotted to receive the immersing wheel 14. The grooved immersing wheel14 projects downwardly into the tank 2 to within a short distance of thebottom there- 'opening 11 of the cover 3, the twine passes through atension box A which is secured to the inner face of the cover 3, thesaid tension box serving both to produce the necessary tension in thetwine and also to prevent the preservative fluid from splashing outthrough the guide opening 11. Mounted within the tension box A are therollers Y 17 and 18, the roller 17 being mounted upon a shaft 19 andbeing fixed, while the roller 18 is mounted upon a shaft 2O and ismovable toward and away from the fixed roller 17. The ends of the shaft20 are slidably mounted within suitable guide slots formed in the sidesof the tension box A, the extremities of the shaft projecting beyond thesides of the tension box and being secured in any suitable manner as bymeans of the pins 22 to slides 23. These slides 23 are provided with thelongitudinal slots 24 which loosely receive the projecting ends of theshaft 19 upon which the fixed roller 17 is mounted, the ends of theslides 23 being engaged by tension springs 25 which normally tend todraw the movable roller 18 toward the fixed roller 17 so as to cause thetwo rollers to securely grip the twine 13 which passes between the same.The extremities of the shaft 19 cooperate with the slots 24 of theslides 23 to aid in the support of the slides and also to direct theslides in their longitudinal' back and forthv movement, while the slo-ts21 in the sides of the tension box A serve as guides for the ends of theshaft 2O upon which the movable roller 18 is mounted. The tension in thesprings 25 may be adjusted as may be found necessary for the purpose ofregulating the tension produced in the twine 13, and for this purposethe ends of the springs 25 are shown as secured to adjusting screws 26which are threaded within 4brackets 27 projecting from the sides of thetension box A.

As the twine 13 emerges from the casing 1 through the guide opening 12in the cover thereof, it passes through the second tension box B whichis secured to the top of the cover, a suitable packing member 28 beingshown as interposed between the bottom of the tensionbox B and the topof the cover 3 so as to produce a tight joint therewith and cause thepreservative fluid to be retained within the box B until it may flowback into the tank 2 through the guide opening 12. The cover 29 of thetension box B is provided with an outlet opening 30 for the twine and ishinged to the box as indicated at 31 so that it can be readily swungLupwardly for the purpose of enabling access to be obtained to thetension rollers on the interior of the box. The swinging end ofa thecover 29 is shown as Vprovided with a hasp member 32 which engages astaple oi" like member 33 at the end of the box B, a

padlock 34 or other suitable member being adapted to be applied to thestaple for the purpose of locking the cover in a closed position. Thetwine 13 as it passes through the tension box B is engaged by a ixedtension roller 35 and also by a movable tension roller 36, the tworollersacting as a wringer to remove the surplus amount of thepreservative fluid from the twine, and also cooperating with the tensionrollers of the box A to produce the necessary tension in the twine. Thefixed roller 35 is mounted upon a shaft 37, while the movable roller 36is mounted upon a shaft 38, the ends of the shaft 38 being engaged by ayoke 39, while the extremities of the shaft are loosely received withinsuitable guide slots 40 which are shown in the present instance asformed in plates 41 embedded in the sides of the box B, the said platesbeing also shown as provided with depressions to receive the ends of theshaft 37. Y The cross bar of the yoke 39 is slidably mounted upon aguide bolt 42 which projects inwardly from Vone end of the tension boxB, a coil spring 43 which surrounds the bolt being `interposed betweenthe yoke and the box B so as to normally tend to move the cross bar ofthe yoke 39 outwardly toward the yhead 42EL of the bolt 42. The movableroller 36 is thus held by the spring 43 in a yielding engagement withthe twine so as to compress the twine against the fixed roller 25 andthereby remove any surplus amount of the preservative fiuid from thetwine. The end of the bolt 42 passes through the end of the box B andhas a nut 44 applied thereto, the tension in the spring 43 beingadjustable by tightening or loosening the nut 44 as may be foundnecessary.

In the operation lof the device the casing 1 may be mounted upon abinder or other machine in any suitable manner so that the twine may becaused to pass through the j casing and be treated by the preservativefluid within the tank 2 before being fed to the machine. rlfhe rollerswithin the tension boxes can be readily adjusted to obtain the necessarytension in the twine, and twine thus treated with a preservative fluidwill be immune from the attacks of grasshoppers, Y

crickets, and other insects, as well as from the ravages of mice androdents. W'here the twine curing device is used in connection with abinder, the bundles ofv grain will remain intact and the loss usuallyoccasioned through the gnawing of the twine by insects and mice and theconsequent breakage thereof thereby avoided. The use of the twine curingmachine is not restricted to binders, however, since it may be employedin connection with any machine using twine, or merely for the purpose oftreating twine for various farm and domestic uses.
